Method benchmark java

Performance - java expensive method call - stack, If it's a performance issue, the jit in your jvm will inline it. in java, method calls are so close to free that it isn't worth thinking about it. that being said, there's a different issue here. namely, it is bad programming practice to call an overrideable method (i.e., one that is not final, static, or private) from the constructor. Java performance - memory runtime analysis - tutorial, The method at the top of the stack is always the current running method for that stack. threads have their own call stack. 2.5. escape analysis. if the jvm identify this it may decide to create the object on the stack, increasing performance of the java program. 2.6. memory leaks.
